Former Goldman Sachs trader Pierre-Henri Flamand's hedge fund has lost money and now he's about to lose partners.

Oliver Haslam and Casper Lund will leave Edoma Partners, according to a note to clients viewed by Bloomberg News.

The event-driven hedge fund, founded by Flamand in 2010, is down 6.9% since inception and its assets have fallen roughly 50% over the past year to $1.17 billion. That figure is set to increase as outstanding redemption requests—including one from Blackstone Group—are honored, says Bloomberg.

Flamand, the former of head of Goldman's largest proprietary trading desk, had raised over $2 billion for the fund.

Prior to joining Edoma, Haslam had worked at other hedge funds, including Citadel and Elliot Management while Lund had previously worked at Morgan Stanley and Goldman Sachs.
